You'll help build and maintain the on-site HPC infrastructure and scientific computing environments that hard-science users depend on daily, working closely with the software team to build scalable, resilient tooling that lets engineers focus on their science, not their infrastructure. You'll serve as a go-to resource for engineering teams navigating HPC and scientific computing questions, and grow into ownership of specific systems and tooling areas. The ideal candidate is patient and organized, comfortable managing a steady volume of cross-disciplinary requests, and capable of digging into complex legacy stacks to find and fix root causes. The infrastructure and tooling you build will help design, run, and mass-produce the first high-temperature gas-cooled portable microreactor ever to be commercialized., * Support workflows, tooling, and performance for scientific computing, including Ansys, STAR-CCM+, and Abaqus, covering licensing, environment setup, job orchestration, and results infrastructure. * Serve as a resource for engineering teams, fielding HPC questions, software issues, and infrastructure needs from nuclear, thermal, materials, mechanical, and electrical engineers, and translating them into actionable work. * Triage inbound infrastructure requests, HPC/MPI/Linux debugging, and job failure analysis, prioritizing effectively and communicating clearly across stakeholders. * Help modernize legacy scientific computing systems and tooling, migrating to current stacks to improve maintainability, performance, and developer experience. * Partner with DevOps engineers to maintain systems across AWS and on-premises Linux environments, supporting high availability, security, and performance for mission-critical workloads. * Contribute to tools supporting build systems, testing frameworks, deployment automation, and developer environments., * Must be willing to work extended hours and weekends as necessary to accomplish our mission. ## Related Videos - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Cloud Vendor Lock-In - Is it just a new version of the Database Abstraction Layers?](https://www.wearedevelopers.com/videos/1185-cloud-vendor-lock-in-is-it-just-a-new-version-of-the-database-abstraction-layers) - [Running Secure Life Science Research at Scale using Hybrid GPU HPC and Kubernetes 🧬](https://www.wearedevelopers.com/videos/100355-running-secure-life-science-research-at-scale-using-hybrid-gpu-hpc-and-kubernetes) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Forget Developer Platforms, Think Developer Productivity!](https://www.wearedevelopers.com/videos/1121-forget-developer-platforms-think-developer-productivity) - [Colorful quantum randomness](https://www.wearedevelopers.com/videos/100257-colorful-quantum-randomness) ## Related Articles - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard)
